Abstract
An apparatus (1) for supporting an explosive device (13) including a base member (3), one or more support members (11) and a fluid aperture (19). The base member (3) includes a base member aperture (5) to provide a passage (7) to a base chamber (9) of the base member (3). The one or more support members (11) are telescopically receivable through the base member aperture (5) and into the base chamber (9), wherein the one or more support members (11) support the explosive device (13). The fluid aperture (19) allows pressurised fluid into the base chamber (9) to force the one or more support members (11) towards an extended configuration (23) such that at least part of the one or more support members (11) are telescopically extended out of the base chamber (9).
Claims22
An apparatus for supporting an explosive device comprising:
- a base member comprising a base member aperture to provide a passage to a base chamber of the base member;
- one or more support members telescopically receivable through the base member aperture and into the base chamber, wherein the one or more support members support the explosive device;
- and
- a fluid aperture to allow pressurised fluid into the base chamber to force the one or more support members towards an extended configuration such that at least part of the one or more support members are telescopically extended out of the base chamber.
An apparatus according to any one of the preceding claims further comprising a valve associated with the fluid aperture, wherein the valve is configurable to inhibit flow of pressurised fluid out of the base chamber via the fluid aperture.
An apparatus according to any one of the preceding claims further comprising:
- an interface at the base member, wherein the interface is selectively connectable to an interface head associated with a mining machine.
An apparatus according to any one of the preceding claims wherein the one or more support members comprises:
- a first support member comprising a first support aperture to provide a passage to a first support chamber of the first support member, wherein the first support chamber is fluidly connected to the base chamber;
- and
- a second support member telescopically receivable through the first support aperture and into the first support chamber,
- wherein the fluid aperture allows pressurised fluid into the base chamber and the first support chamber to force the first and second support members towards the extended configuration such that at least part of the second support member is telescopically extended out of the first support chamber and at least part of the first support member is telescopically extended out of the base chamber.
An apparatus according to any one of the preceding claims wherein one or more of the support members and the base members comprise one or more tubular members.
An apparatus according to any one of the preceding claims wherein one or more of the support members and the base members are polymer members.
An apparatus according to any one of the preceding claims further comprising one or more additional members, wherein the additional members are telescopically receivable into the base chamber through a second base member aperture of the base member, wherein the pressurised fluid into the base chamber forces the one or more additional members towards a second extended configuration.
An apparatus according to any one of the preceding claims further comprising an extension, wherein the extension is located at the base member, or the one or more additional members, and wherein the extension is structurally weaker that the base, support members, or additional members such that on excess pressure in the base chamber the extension compresses before structural failure of the base member, support members, or additional members.
